ELECTRIC-LIGHT FIXTURE FOR MUSIC-STANDS.

SPECIFICATION forming part of Letters latent No. 513,113, dated January23, 1894.

Application filed September 19, 1893- Serial No. 485,762, (No model.)

To all whom it may concern:

Be it known that I, WILLIAM J. KELLY, residing in Boston, in the countyof Suffolk and State of Massachusetts, have invented an Improvement inIncandescent-Electric-Lamp Fixtures for Music-Stands,of which thefollowing description, in connection with the accompanying drawings, isa specification, like letters on the drawings representing like parts.

This invention relates to an incandescent electric lamp fixtureespecially designed and adapted to be attached to a music stand, wherebythe light from the incandescent lamp may be cast or diffused downward inthe form of a sheet over the music on the stand, in sufficientquantityto enable the music to be easily seen, but not in such quantity as tolight up the space in thevicinity of the stand.

This invention is more particularly adapted to be used on music standsemployed in the orchestra of theaters, halls, and like places,

wherein in certain scenes of a play, it is de-' sired to have theauditorium or house as dark as possible, in order to obtain the bestpossible stage effect. I

Prior to this invention, the stage effects desired have been onlypartially successful, owing to the factthat the light from theorchestrawas plainly visible from the auditorium and was suificiently bright topartially spoil the efiect of the scene.

In accordance with this invention,the music stand, employed by one ormore musicians, has attached to it an incandescent electric lampfixture, preferably made as a tubular hollow body within which the lampor lamps are located, and which is provided with a longitudinal slit oropening through which the light from the lamps may pass in the form of asheet onto the music score on the stand. The hollow body is preferablymade movable or adjustable, so that the slit or opening may be changedwith relation to the music stand. These and other features of thisinvention will be pointed out in the claims at the end of thisspecification.

Figure 1 is a perspective view of a music stand provided with anincandescent electric lamp fixture embodying this invention; Fig. 2, aside elevation on an enlarged scale and partially broken out of thestand and its attached fixture shown in Fig. 1, and Fig. 3, an

enlarged detail in section and elevation to be referred to.

The music stand with which my improved fixture is used, may be of anyusual or suitable construction, it being shown asconsisting of a musicsupport or rack a provided with the depending red a vertically movablein the hollow stem or upright a erected from the base a The rack a hasattached to it an incandescent electric lamp fixture, preferably made asherein shown, it consisting of a hollow body I) provided with alongitudinal slit or opening 1) preferably extended substantiallythelengthofthe said body,thelatterbeingsupported at its opposite endsabove the rack Ct. The hollow body Z) incloses one or more incandescentelectric lamps 19 but in the presentinstance only one lamp is shown, andwhen a single lamp is used, the hollow body b is made with one endclosed and its opposite end open, into which the incandescent lamp 1) isextended, the latter being provided with a socket b of any usual. orsuitable construction, and which, as herein shown, has mounted upon it acap 19 into which the open end of the body I? is extended, and which capin the present instance supports the said body at one end, its oppositeend being supported, as shown, by a collar or ring 11 secured to orforming part of a bar or arm b fastened to the rack a in any suitablemanner. The socket b is provided with the usual switch key b and thesaid socket is fastened in any suitable manner to a tube or hollowsupport b secured to the rack a, the said support or tube being shown asextended through a sleeve or hollow portion b of a plate or bar bfastened to the rack or as by screws b, the tube or hollow support bbeing adj ustably secured to the sleeve 19 by a set screw o The hollowstandard a is provided as herein shown with a collar 0 provided with aring or eye 0', through which passes the conducting cord 0 containingthe conductors 0r wires leading to the lamp terminals, thesaidconducting cord passing through the hollow support or tube 19 Thetubular body I) is rotatable in the collar or ring 6 and in the cap I),and may be turned to bring the slit or opening 19' into any desiredposition with relation to the rack a. The said body is further ad- 3'ustable with relation to the rack a, by means of the hollow support ortube I) being adj ustably secured to the rack a by the set screw I2whereby the slit 1) may be brought substantially parallel with the musicscore supported on the rack a and not herein shown, the end of the bodyI) in the collar I) being fitted therein somewhat loosely to'permit of alimited movement of that end of the body I). It will thus be seen thatthe light from the lamp is cast or diflused through the slit or openingI) in the body I), which permits of only a small quantity of light inthe form of a sheet to pass out onto the score or music on the rack, andby reason of this light being deflected downward, the auditorium in theimmediate vicinity of the orchestra is not lighted, and consequently thedesired stage eflect may be successfully obtained. Access may be had tothe lamp for repairs or other purpose, by moving the hollow body b outof the cap I) and through the ring or collar U.

I have described the hollow body I) as closed at one end, but it isevident that this closed end may be left open and fitted in a capsimilar to the cap I), or in other words, the cap I), the lamp 12 socketb and the pipe I) may be duplicated, so that the hollow body I), mayhave a lamp 12 extended into each end of it.

I claim- 1. The combination with a music stand, of an incandescentelectric lamp fixture attached thereto and consisting of a hollow bodyextended in the direction of the length of the stand and containing anincandescent elec-- tric lamp and provided with a longitudinal.

light emitting slit or opening, substantially as described.

2. The combination with a music stand, of an incandescent electric lampfixture attached thereto and consisting of a hollow body containing anincandescent electric lamp provided with a light emitting slit oropening, and a support for said hollow body adjust- 4. The combinationwith a music stand, of,

an incandescent electric lam p fixture attached thereto and comprising ahollow body closed at one end and provided with a longitudinal slit oropening, a support for the closed end of the said body consisting of acollar or ring b a cap 19 supporting the open end of the hollow body, alamp socket on which said cap is mounted, and a hollow support attachedto the said stand and to which the said socket is secured, substantiallyas described.

5. The herein described fixture for incandescent electric lamps, itconsisting of a tubular body b closed at one end and provided with alongitudinal slit or opening I), a cap to close the opposite end of thesaid body, and a lamp socket supporting said cap, substantially asdescribed.

6. The combination with a music stand, of an incandescent electric lampfixture consisting of a hollow body containing an incandescent electriclamp and provided with a light emitting slit or opening, and a hollowcord-conducting support [or said fixture attached to the said stand,substantially as described.
